Abstract: A method includes, in accordance with some implementations, sending, a measurement station, a trigger frame to a signal source station, where the trigger frame carries pilot format information, and the pilot format information is used to indicate a sending time point of a signal frame triggered by the trigger frame, a quantity of times for sending the signal frame, and a transmission mode of pilot information in the signal frame. The measurement station receives an illumination frame from the signal source station, where the illumination frame is the signal frame triggered by the trigger frame. The measurement station analyzes pilot information in the illumination frame to obtain sensing information in the illumination frame, where the sensing information is used to indicate physical information of an object surrounding the signal source station and the measurement station.

Abstract: This application provides a method and an apparatus for sensing measurement. In a technical solution of this application, a transmit end of data may send an indication frame to a receive end of the data, where the indication frame may indicate a spatial mapping matrix used by the transmit end of the data to send the data to the receive end of the data. In this way, the receive end of the data can eliminate impact of spatial mapping on channel state information based on the spatial mapping matrix, to obtain actual channel state information, thereby completing sensing, positioning, and the like on an ambient environment or a passive target by using the obtained actual channel state information.

Abstract: A method includes: A first device sends a first BRP frame, to indicate a second device to evaluate a variation of CSI from the first device to the second device in an initiator beam refinement protocol transmit sector sweep procedure. The first device sends a plurality of first BRP-TX PPDUs, where the plurality of first BRP-TX PPDUs are used to evaluate the variation of the CSI from the first device to the second device. The first device receives a second BRP frame carrying a first sector information list, where the first sector information list is used to feed back one or more sending sectors whose variation of the CSI from the first device to the second device is greater than a CSI variation threshold.

Abstract: A data frame sending method includes: encoding first information by using a first encoder, to generate a first coded segment and a second coded segment; interleaving the first information by using M interleavers, to generate M pieces of information, where the M pieces of information one-to-one correspond to the M interleavers; encoding the M pieces of information by using the first encoder, to generate 2M coded segments; generating a data frame, where the data frame includes N coded segments, and the N coded segments include all or a portion of the first coded segment, the second coded segment, and the 2M coded segments; and sending the data frame through at least two subchannels in N subchannels.
